Which speaker is the master of IMAGING ????

The best imaging I've ever heard comes from single-driver speaker systems. The true point-source radiation is a key factor, in my opinion, combined with the lack of passive crossover problems. However, single-driver systems have a limitation in low bass response, rolling off at about 40Hz on the bottom end.

I agree with Sean about Focal drivers. Another excellent adaptation of these drivers is the Rosinante Dulcinea speaker. A 2-way stand-mounted monitor that does it all, with the exception of very low bass. Still, in the right room they can go down to 35hz. They're not picky about set-up and at 91dB efficiency can be driven with a low-powered amp. I use a 13 watt Art Audio Diavolo SET amp in a 20' x 23' room and only have to turn the volume to the 9:00 position.

These are hand-built by Ric Cummins, the inventor of the Argent Room Lens. They are hard to come by on the used market since those who own them tend to hold on to them they're so good. You can take a look at them on the Rosinante website at www.roomlens.com. I don't work for Ric, just love his speakers and cables!

Wilson W/P 7's. They also make use of Focal drivers on the top end.

Spica TC50 and Quads have superb imaging. Also, I've heard a few single driver (Jordan, Fostex, and Lowther) speakers with great imaging too. Single driver speakers usually have more precise imaging, depending on size and execution. As a general rule, small 2-way and smaller single driver speakers have better "imaging" than larger multiple driver speakers.

Furthermore, I've never heard a speaker with 3 or more drivers produce imaging that was convincing. They all seem to distort scale and proportion, albeit while playing louder over a greater range.

A few years ago, I heard the MBL 101s (the watermelon-shaped speakers) with a single sub driven with the-then-top of the line VAC CPA pre and a model of the Vintage amps. On an orchestral recording, musicians each had their own little 3D spot where they sat. When you walked towards the speakers, none of the their positions moved. Once you were past the front line of the speakers, still facing forward, the first lateral rows of musicians were BEHIND you, just like you were walking past them in real life with you moving closer to the woodwinds. The hairs on the back of the neck went up then! Uncanny and WAY outta my price range! Also, not even close on solid state, so much so, I don't recall what was used.
